I am excited to share my first publication as a co-author at UofL with my fellow PhD student, ISAAC OFFEI, MGIOC, S.M.ASCE. Isaac applied hydrophobic materials in cement mortar to prevent ASR-induced deterioration. We found that coating aggregates with hydrophobic fumed silica are more effective at reducing ASR-induced expansion compared to directly integrating the hydrophobic materials. Thank you, ISAAC OFFEI, MGIOC, S.M.ASCE, and Dr. Zhihui Sun, for allowing me to put a cherry on top of the work. The paper was published in Construction and Building Materials (IF. 7.4).

🌟 What a fruitful May! 🌟 Submitted papers at different times, but surprisingly, many of them got published this month! Thrilled to share the publication of our latest research paper titled "Use of Hansen Solubility Parameters (HSP) in the Selection of Highly Effective Rejuvenators for Aged Bitumen" in Road Materials and Pavement Design. 📄 This study delves into using Hansen Solubility Parameters to identify effective rejuvenators for aged bitumen. Rejuvenators with similar HSP values to bitumen, particularly those with greater HSP radii, show higher rejuvenation efficiency, paving the way for more sustainable pavement construction. Notably, this paper is the first to investigate the correlations between HSP and rejuvenation efficiency. Our findings could also potentially address concerns regarding the compatibility between aged/rejuvenated asphalt binders and fresh binders in future applications. A heartfelt thank you to my amasing co-authors Anand Sreeram, Wei Xia, Wei Si, Haopeng Wang, Lu Zhou and Gordon Airey and everyone who supported this research. #Research #Publication #CivilEngineering #SustainableConstruction #BitumenRejuvenation #HansenSolubilityParameters

Olajide Ipindola, our PhD Candidate, will be presenting two research studies at the 14th Advances in Cement-based Materials conference, which will take place from June 19-21 at Missouri S&T in Rolla, Missouri. Olajide's research focuses on the additive manufacturing of cement-based materials, specifically developing performance-based standards for reinforced 3D-printed concrete structures. His presentations at the conference are titled: - Effect of Temperature and CSA Dosage on the Hydration Kinetics and Phase Assemblage of Blended OPC – CSA Systems (No. 3325) - Hydration and Microstructural Evolution of Seawater-mixed Calcium Aluminate Cement (No. 3324) We look forward to the insightful contributions and discussions that these presentations will bring to the conference. #CementInnovation #CSA #3DPrintedConcrete #CivilEngineering #SustainableConstruction #MaterialsScience #Structures Clarence M.

I am very pleased to share with our recent works about physical hardening in bitumen characterized by 4-mm DSR has published on Materials and Structures RILEM Association. 4-mm DSR is a emerging technology to measure the low-temperature rheology together with BBR tests. What kind of interesting phenomenon will occur as combining 4-mm DSR and physical hardening?

Sharing insights from my PhD project in the #buildingmaterialsgroup at #Chalmers on #lowcarbon binders! 🌱 During my research on #lowkaolinite #natural clays in Sweden, it became clear that the reactivity of clays is closely tied to activation methods. Especially in the context of #heterogeneous, low kaolinitic #clays, their inherent low pozzolanicity make them less appealing for industrial applications. While calcination or mechanochemical activation (MCA) are commonly used for activating clays, we found that combining these activation methods can significantly modify physical and chemical properties which in turn can improve clay reactivity. Our recently published #paper explores these findings, highlighting the relationship between activation treatments, particle sizes, specific surface areas, and reactivity of #lowkaolinite and #lowreactive clays. We also discuss how impurities in heterogeneous clays affect their reactivity. Understanding these nuances is crucial for utilizing the potential of #lowkaolinite #clays as #supplementarycementitiousmaterials. Excited to continue exploring their functional and durability benefits! Do read our paper here at: https://lnkd.in/egjYPGme I will look forward to hear your thoughts 😊 We thank Formas, a Swedish Research Council for Sustainable Development, Vinnova and Family Thomas Foundation, for the financial support towards this study.  Arezou Babaahmadi Liming Huang Springer Nature Group Chalmers University of Technology Thomas Concrete Group AB #lowkaoliniteclay #lowcarboncement #SustainableMaterials #buildingmaterialsgroup

I am glad to share that the second paper related to my PhD has been published and is now available at: https://lnkd.in/gQxpeT7B My PhD study focused on the carbonation of cement pastes as a method for CO2 sequestration and the production of novel low-carbon cementitious materials. This study investigated the reactivity of carbonated cement pastes, which is arguably the most important property of this material since it heavily dictates the strength development of cement-based materials and, consequently, its future applicability. To better understand the factors controlling the reactivity, we designed this study to evaluate the reactivity of carbonated pastes originating from different cement compositions and produced under different carbonation conditions. The findings from this study demonstrate that all carbonated pastes exhibited comparatively fast reactivity and are suitable for incorporation in cement mixtures, thereby, allowing a lower CO2 footprint of cements. Finally, I would like to thank the massive support from my supervisors, Jørgen Skibsted and Ruben Snellings. This project was a great opportunity to expand my research skills and contribute to a more sustainable future of construction materials. #CO2sequestration #CCU #ConstructionMaterials #PhDlife

Hello! I am happy to share with you the first published paper from my PhD. I would like to thank Professor David Gregoire and Professor Céline Perlot Bascoulès for their supervision during my PhD and Olivier Nouailletas for his contribution to this work. A special thanks to Professor Fernando Lameiras for his help with the statistical modelling support. For this paper, we proposed a methodology to optimise the packing of non-spherical particles in a granular skeleton to reduce the intergranular porosity. We found out that the granular skeleton optimisation was a key point to enable the complete aggregate replacement in mortar. Also, the adjustment of cement content on top of the granular skeleton optimisation can restore the mechanical properties of the 100% aggregate replacement in the oyster shell mortar, particularly in flexural tension. This work helped us to validate a full aggregate replacement with crushed oyster shells whilst keeping desirable mechanical properties.
